Answer:
x= 55
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+70 =180
Subtract 70 from each side
2x+70-70=180-70
2x= 110
Divide by 2
2x/2 = 110/2
x= 55
If I did this correctly it simplifies to 0 = 8. So I think B is the correct answer. Hope this helps!!
So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6. <span />
Answer:
C and A
Step-by-step explanation:
expand the things in parentheses so for C
1/2(x + 16) = 1/2(x) + 1/2(16) = 1/2 x + 8
same process for A
